Title: Combination Fault Current Limiter
Inventor: SARGENT PHILIP MICHAEL
IPC: H02H9/02
Filed: 2011-03-15
Abstract: The Combination Fault Current Limiter (CFCL) controls the fault energy transmitted to the network within a small range irrespective of the size of the fault that it is exposed to. A first superconducting fault current limiter limits a fault current to a level greater than the nominal current, and after a period of time more than one full AC cycle (or more than 5 ms for DC), a second fault current limiter limits the current further to a non-zero value. The period of time may be varied according to the intensity of the fault. The CFCL is able to react quickly to limit fault energy but still allow a circuit breaker to recognise the fault.

Title: Passive circuit for signaling synchronization information over an Ethernet cable, with inductive coupling through a common magnetic core
Inventor: KIDGER ALEXANDER CHARLES
IPC: H04L5/20
Filed: 2012-12-24
Abstract: This invention is concerned with superimposing signalling information, such as a synchronisation signal, onto data signals transmitted over two or more pairs of wires contained within a cable. The pairs of wires connect a first data signal source (10, 14) and a first data signal receiver (12, 16). A portion of each wire pair is wound around a magnetic core (28). A further winding (30) is wound around the core (28). A further signal source (24) is coupled to the further winding (30) and a further receiver (36, 26) is coupled to the wires to receive the further signal. The windings around the core are arranged to apply the further signal to the wire pairs as a common-mode signal. This allows the further signal to be transmitted to the further receiver without affecting the signal transmitted between the first signal source (10, 14) and the first signal receiver (12, 16) and with only minor modification of the cable (18). The invention thus provides a phantom circuit for transmitting signalling information. The invention may be applied to Ethernet transmissions from the top to the bottom of a radio mast. The signalling information may be extracted at the receiver by means of capacitive coupling (34).

Title: Sleep mode operation for networked end devices
Inventor: HA WAI-LEUNG
IPC: H04W4/00
Filed: 2013-07-25
Abstract: A technique provides apparatuses, methods, and computer readable media for sending sleep information from an end device to a central unit of a network, in which the wake-up time of the end device is aligned to the scanning time for the central unit. The technique addresses at least two considerations: the clock accuracy of the end device is accounted for, and the reason that the end device requests sleep mode operation is provided. To address the above considerations, the end device may send its clock tolerance information and/or request for sleep mode (RSM) command to the central unit once the end device is connected via the network. The central unit may then adjust the scanning time based on the clock tolerance information. If the central unit receives a response from the end device during the adjusted scanning time, the central unit deems that the end device is still connected.
